Hi all, Ive got a 71 International fleetstar 2110 with a 549 v8 in it. I got a good deal on it and i will use it to haul hay once or twice a year, and maybe a little dirt/rock here and there. 

I first drained gass and cleaned tanks. I fixed the fuel pump wiring. I filled the bowl and threw a battery in it, it fired up and ran on 5 cyclinders. Plug wires were severed or missing. So i put new wires, cap, points and condenser, plugs and rotor in. now it wont fire at all.

Ive got power to my coil, and power from to coil to the points. But no spark at the plugs. The condenser was new about 15 years ago, so it shouldnt be a cheap garbage one. The plug wires were universal ones, and i havnt had good experiences in the past with those, could it be as simple as bad plug wires? Is it worth the 80 bucks to get the electronic points conversion? i know that made a huge difference with my Y-block. The only thing i havnt changed is the coil, but, it ran before i did anything to it. So i know its something I put on or did. Any help is greatly appreciated. 

Also, if someone could tell the difference between a 549 and a 537, that would be helpfull. Was told it was a 549, but most of those ive seen have distributer in the front, not the case with this one. 20220206_123610.thumb.jpg.63e817058ddec95b49c7d9fdccde35ae.jpg20220206_122541.thumb.jpg.a9da67bd273377fdd6efa12ee7aa2a6e.jpg20220206_122644.thumb.jpg.95bc2491670cb5ce500e3b1b16328252.jpg

Thanks in advance

Are these engines timed off of #8 like a 392? If it's backfiring through the intake, then the plug wires may be on wrong.

Yes i think they are timed off #8.

check firing order

check timing

 

I got the firing order off the intake manifold. And have checked it several times. Is there a way timing could get off besides physically turning the distributor?

check your weights in distributor, for free movement, the swivel they mount on for play or oblong shape........springs on weights on correct or not stretched or worn out.......etc.

vacuum advance unhooked?  is the rod frozen in place?

Are the screws used to put your new points in the same length as the originals?  Not longer poking down into someplace they shouldn't......

Okay. Im trailering it back to the shop tomorrow. Then I can get a better look at things like that. Thanks for all the help today, i gained a little. 

Side note, anyone know how to release the air brakes on this truck?

My 392 has the distributor installed so that it's timed off of #1. Had a similar problem when I put new wires on it. Instead of monkeying with the distributor, we just moved the wires. You can get the timing mark on tdc and see where the rotor is pointing.

Okay, ill give that a shot

If your points are set way wrong it will affect your timing and can make it backfire. If you have the plug wires wrong it can  make it backfire.

Make sure the points are set correctly.  Verify TDC. Make sure the spark plug wires are correct.

Thx-Ace
